News about Mars: Space geologist named recipient of the 2012 US-Presidential Early Career Award

Global mosaic of 102 Viking 1 Orbiter images of Mars taken on orbit 1,334, 22 February 1980. The images are projected into point perspective, representing what a viewer would see from a spacecraft at an altitude of 2,500 km. At center is Valles Marineris, over 3000 km long and up to 8 km deep. Note the channels running up (north) from the central and eastern portions of Valles Marineris to the area at upper right, Chryse Planitia. At left are the three Tharsis Montes and to the south is ancient, heavily impacted terrain. Photo: NASA / USGS / Wikimedia Commons

(January 2014) US-President Barack Obama has named Dr. Rossman P. Irwin III, a geologist at the Smithsonian’s National Air and Space Museum in Washington D.C., a recipient of the 2012 Presidential Early Career Award for Scientists and Engineers. Irwin, a staff member in the museum’s Center for Earth and Planetary Studies, was recognized for his research in the role of water in shaping the landscape of Mars.

The three most significant findings by Irwin and his colleagues include evidence of complex climate change on Mars, river channels that are similar in size to those found on Earth, and Martian lakes that overflowed to produce large floods. The research suggests a variable change in climate rather than a simple decline.

The department performs original research and outreach activities on planetary science, terrestrial geophysics and the remote sensing of environmental change. Its scope of study includes work on Mercury, Venus, the moon, Mars, asteroids and some satellites of the outer solar system, as well as corresponding field studies in analog regions on Earth.

After receiving his doctorate from the University of Virginia’s Department of Environmental Sciences in 2005, Irwin completed a post-doctoral appointment at the Smithsonian in 2010. From 2010 to 2012, he worked for the Planetary Science Institute as a visiting scientist at NASA’s Goddard Space Flight Center. He received a bachelor’s degree in geological sciences from Virginia Polytechnic Institute in 1997 and a master’s in environmental sciences from the University of Virginia in 2000.

„The impressive achievements of these early-stage scientists and engineers are promising indicators of even greater successes ahead,” said Obama. „We are grateful for their commitment to generating the scientific and technical advancement that will ensure America’s global leadership for many years to come.”

Along with 97 other federal researchers, Irwin will receive his award in a ceremony early in 2014. The program is coordinated by the Office of Science and Technology Policy within the Executive Office of the President. Awardees are selected for their pursuit of innovative research at the frontiers of science and technology and their commitment to community service as demonstrated through scientific leadership, public education or community outreach.

This mosaic of images from Curiosity's Mast Camera (Mastcam) shows geological members of the Yellowknife Bay formation. The scene has the Sheepbed mudstone in the foreground and rises up through Gillespie Lake member to the Point Lake outcrop. These rocks record superimposed ancient lake and stream deposits that offered past environmental conditions favorable for microbial life. Rocks here were exposed about 70 million years ago by removal of overlying layers due to erosion by the wind. Photo: NASA/JPL-Caltech/MSSS(09.01.2014, USA: 01.09.2014)
